PostgreSQL 22021

PostgreSQL 22021 is an error code indicating that a character in a string is not valid. The literal message is character not in repertoire.

How It Affects Your App

CHARACTER NOT IN REPERTOIRE is an error that occurs when a character is not supported by the database. This can have a significant impact on an application, as it can prevent data from being stored or retrieved correctly. It can also lead to data corruption, as the database may not be able to interpret the data correctly. Additionally, it can cause the application to crash or become unresponsive, as the database may not be able to handle the unsupported character. As a result, it is important to ensure that all characters used in the application are supported by the database.

How To Fix

1. Check the PostgreSQL log files for any errors or warnings that may be related to the PostgreSQL 22021 issue.

tail -f /var/log/postgresql/postgresql-9.6-main.log

2. Check the PostgreSQL configuration files for any settings that may be causing the issue.

cat /etc/postgresql/9.6/main/postgresql.conf

3. Check the PostgreSQL system tables for any inconsistencies that may be causing the issue.

SELECT * FROM pg_stat_activity;

4. Check the PostgreSQL system processes for any issues that may be causing the issue.

ps aux | grep postgres

5. Check the PostgreSQL system memory for any issues that may be causing the issue.

free -m

6. Check the PostgreSQL system disk for any issues that may be causing the issue.

df -h

7. Restart the PostgreSQL server to apply any changes that may have been made.

sudo service postgresql restart

8. Monitor the PostgreSQL server for any further issues that may arise.

9. To assist in monitoring and fixing the PostgreSQL 22021 in question, it is recommended to use an automated database observability tool.
